LRRK2 phosphorylates pre-synaptic N-ethylmaleimide sensitive fusion (NSF) protein enhancing its ATPase activity and SNARE complex disassembling rate [PDF]
Background Lrrk2, a gene linked to Parkinson\u2019s disease, encodes a large scaffolding protein with kinase and GTPase activities implicated in vesicle and cytoskeletal-related processes.

Release and recycling of synaptic vesicles are essential for neurotransmission and synaptic plasticity. To gain mechanistic understanding of these processes, direct measurements of vesicle release and retrieval is indispensable.

Aberrant lysosomal carbohydrate storage accompanies endocytic defects and neurodegeneration in Drosophila benchwarmer [PDF]
Lysosomal storage is the most common cause of neurodegenerative brain disease in preadulthood. However, the underlying cellular mechanisms that lead to neuronal dysfunction are unknown.

Entering neurons: botulinum toxins and synaptic vesicle recycling [PDF]
Botulinum toxins are metalloproteases that act inside nerve terminals and block neurotransmitter release through their cleavage of components of the exocytosis machinery. These toxins are used to treat human diseases that are characterized by hyperfunction of cholinergic terminals.

Ambient but not local lactate underlies neuronal tolerance to prolonged glucose deprivation [PDF]
Neurons require a nearly constant supply of ATP. Glucose is the predominant source of brain ATP, but the direct effects of prolonged glucose deprivation on neuronal viability and function remain unclear.

Recycling of Synaptic Vesicles
Publisher Summary A widely accepted model describes the synaptic vesicle cycle as a modification of the receptor-mediated recycling pathway present in all cells. This pathway, by which cell surface receptors, like transferrin or low-density lipoprotein receptors, are internalized and recycled back to the surface, involves two distinct vesicular ...

Synaptic Vesicle Endocytosis in Different Model Systems
Neurotransmission in complex animals depends on a choir of functionally distinct synapses releasing neurotransmitters in a highly coordinated manner. During synaptic signaling, vesicles fuse with the plasma membrane to release their contents. The rate of

Amyloid-β acts as a regulator of neurotransmitter release disrupting the interaction between synaptophysin and VAMP2. [PDF]
BACKGROUND: It is becoming increasingly evident that deficits in the cortex and hippocampus at early stages of dementia in Alzheimer's disease (AD) are associated with synaptic damage caused by oligomers of the toxic amyloid-β peptide (Aβ42).

FM1-43 reveals membrane recycling in adult inner hair cells of the mammalian cochlea [PDF]
Neural transmission of complex sounds demands fast and sustained rates of synaptic release from the primary cochlear receptors, the inner hair cells (IHCs). The cells therefore require efficient membrane recycling.

Alternate routes to the cell surface underpin insulin-regulated membrane trafficking of GLUT4 [PDF]
Insulin-stimulated delivery of glucose transporters (GLUT4) from specialized intracellular GLUT4 storage vesicles (GSVs) to the surface of fat and muscle cells is central to whole-body glucose.
